I've been happy with my 2011 Nissan Pathfinder Tekna 2.5 manual, which has been owned from nearly new and has always been serviced by Nissan. I've become concerned by recent reports of failure of the rear chassis on the Nissan Navara and Pathfinder. A friend with a 2007 Pathfinder suffered this fault resulting in a write off. The Nissan garage we contacted said the issue is only with 2005 - 2007 vehicles but we could have the car checked at our expense if we wished. My car has no obvious problem other than light surface rust on the chassis. Should I be concerned? The car regularly tows a horse box so works quite hard.
